Painters put brushes to canvas, sculptors take chisels to marble, potters shape clay on a wheel, but the process for handblown glass is, to put it mildly, slightly more obscure.

“I’ll be out in the world selling my work at a festival, and I’ll ask a child if they know what glass is made of,” says Lisa Aronzon, 58, a glass-blowing artist based in Virginia’s Shenandoah Valley. “I’ve actually had a child say, ‘Plastic?’” When Aronzon explains that glass is made of sand, “Their eyes light up. … It seems like magic, or alchemy,” she says. And in a sense, it is.

I’ve never done it but I’ve always been fascinated by glass blowing. I could watch people do it all day long.
